MMH5.5 - Heroes of Might and Magic 5.5

it was done this way to follow the same formula as for other perks
perk = 2 primary skills = 2*3.33% = 6.66% it was reduced to a little less because luck + offensive bonuses stack too well and increase the pace of the game too much in favor of might heroes with high attack stats.

Basically this is why all might hero choices seem weaker. They have a synergy between each other for free (no need for hero to do anything during battle). They are not weak; it is just that they look so compared to what they were.
Cheers.

If 0.0 causes problems, have you tried very small numbers like 0.01, 0.001, etc.?

I don't know; I will ask.

@Magnomagus will try with 0.0, and we will see how it goes.

Also, here is some info on the Combat tree.

The Combat secondary skill is weaker than the others; that is true. This is why all end perks are stronger to compensate - Preparation, armor spikes, Crushing blow + chain attack combo
